BasicTTIImplBase(const TargetMachine *TM, const DataLayout &DL)

Represents a single loop in the control flow graph.

The main scalar evolution driver.

virtual const DataLayout & getDataLayout() const

This pass provides access to the codegen interfaces that are needed for IR-level transformations.

TargetCostKind

The kind of cost model.

PopcntSupportKind

Flags indicating the kind of support for population count.

PartialReductionExtendKind

CastContextHint

Represents a hint about the context in which a cast is used.

The instances of the Type class are immutable: once they are created, they are never changed.

Key for Kernel::Metadata::mArgs.

friend class Instruction

Iterator for Instructions in a `BasicBlock.

This is an optimization pass for GlobalISel generic memory operations.

ArrayRef(const T &OneElt) -> ArrayRef< T >

Returns options for expansion of memcmp. IsZeroCmp is.

Parameters that control the generic loop unrolling transformation.
